Dental biocorrosion can produce a devastating impact on oral health. The restorative phase of the treatment should not cause additional damage of the remaining sound tooth structure. Ultrathin occlusal veneers are a conservative alternative to traditional onlays and complete crowns for the treatment of severe biocorrosive lesions. This strategy is explained in the present case report through a full-mouth rehabilitation of a patient with moderate biocorrosion. Maxillary anterior teeth were restored using the bilaminar technique (lingual direct composite veneers with labial ceramic veneers) and posterior teeth using ultrathin CAD-CAM ceramic occlusal veneers. The technical aspects required for the implementation of this new restorative design are presented with a special emphasis on the control of tooth preparation based on diagnostic wax-up, provisionalization, and the use of CAD-CAM technology.
牙齿生物腐蚀会对口腔健康产生毁灭性影响。治疗的修复阶段不应造成剩余完好牙齿结构的额外损伤。超薄咬合面贴面是治疗严重生物腐蚀病变的一种保守替代方案，可替代传统嵌体和全冠修复。本病例报告通过对一名中度生物腐蚀患者的全口修复来解释这一策略。上颌前牙采用双层技术修复（舌侧直接复合树脂贴面加唇侧陶瓷贴面），后牙采用超薄CAD-CAM陶瓷咬合面贴面。介绍了实施这种新修复设计所需的技术要点，特别强调基于诊断性蜡型、临时修复以及CAD-CAM技术应用的牙体预备控制。
